Benefits of technology

The present disclosure describes a seatbelt device that improves the comfort and safety of an occupant by providing better restraint and reducing the feeling of being constricted.

Problems solved by technology

However, in the four-point seatbelt device described above, the occupant experiences a sense of constriction due to the body of the occupant being restrained by the two-point seatbelt in addition to the three-point seatbelt.
Moreover, the occupant has to put on the two-point seatbelt after putting on the three-point seatbelt, making the seatbelt device frustrating to wear.

Abstract

In a four-point seatbelt device including a three-point seatbelt and an automatic belt, the automatic belt is actuated to dispose an anchor at a standby position after the three-point seatbelt has been placed over an occupant. During this operation, the anchor is disposed further to a rear side than a field of vision of the occupant facing toward a front side, for example, and a second webbing is placed in standby in an unrestrained state with respect to the occupant. Moreover, in a case in which a vehicle collision has been predicted by a PCS control section, the automatic belt is actuated to place the second webbing over the occupant automatically.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 USC 119 from Japanese Patent application No. 2015-148574 filed on Jul. 28, 2015, the disclosure of which is incorporated by reference herein.BACKGROUND[0002]Technical Field[0003]The present disclosure relates to a four-point seatbelt device.[0004]Related Art[0005]A four-point seatbelt device described in Japanese Patent Application Laid-Open (JP-A) No. 2007-230335 includes a three-point seatbelt and a two-point seatbelt. Specifically, after the three-point seatbelt has been placed over an occupant, the two-point seatbelt is placed over the occupant so as to intersect with a shoulder belt of the three-point seatbelt. Both shoulders of the occupant are thereby restrained by the three-point seatbelt and the two-point seatbelt respectively, thereby enabling improved occupant restraint performance. Note that vehicle seatbelt devices are also described in Japanese Patent No. 2784079, and in JP-A Nos. S61...
